You have designed a network to support two offices connected by a T1. Your router serial interfaces will be configured with encapsulation PPP. What will happen to your EIGRP neighbors if there is an LCP failure once your network is implemented?

Your neighbors will drop after the EIGRP timers expire.

Your neighbors will stay up because the link has not gone down.

Your neighbors will drop immediately.

Your neighbors will drop and EIGRP will begin the query process.

An MPLS service provider is offering a standard EoMPLS-based VPLS service to Customer A, providing Layer 2 connectivity between a central site and approximately 100 remote sites. Customer A wants to use the VPLS network to carry its internal multicast video feeds, which are sourced at the central site and consist of 20 groups at 5 Mb/s each. Which service provider recommendation is the most scalable?

Replace VPLS with a Layer 3 MVPN solution to carry the streams between sites.

Use GRE tunnels to carry the streams between sites.

Answer: C

You are designing a large Frame Relay WAN for a customer. The routing protocol is OSPF. What is the effect on the routing table if the WAN interfaces are configured as point-to- multipoint?

Only a route for the DR will be present in the routing table.

Configuring point-to-multipoint has no effect on the routing table. The route that is configured with the area command will be seen in the routing table.

Multipoint interfaces dynamically add the network of the connected interface.

Multipoint interfaces dynamically add a /32 route for each neighbor in the WAN.

A Mobile Service Provider would like to design and deploy an Ethernet service which has similar physical link failover/failback characteristics on the active/backup links as the APS/MSP SONET properties. Which Layer 2 services should be considered to address this design feature?

Port-Channel

MLPPP

Flex Link

Ethernet Pseudowires

Answer: C

Refer to the exhibit.

When designing an MPLS-based LAN extension between DC-1 and DC-2, what are three advantages of deploying VSS? (Choose three.)

Layers 2, 3, and 4 flow-based load balancing

native VSS and MEC failover without using scripts

sub-second failover

required to configure VPLS

failover time depends on Cisco IOS EEM and STP convergence

limited VLAN-based VPLS traffic hashing

Answer: A,B,C

Your company requires two diverse multihop External Border Gateway Protocol peerings to a partner network. Which two methods would you use to improve lost peer detection? (Choose two.)

Use Bidirectional Forwarding Detection for the peers.

Use Selective Address Tracking and match the peers.

Use subsecond keepalives for the peers.

Use subsecond hold timers for the peers.

Use Fast Peering Session Deactivation for the peers.

Use subsecond minimum route advertisement Interval timers for the peers.

Answer: B,E

You are tasked to design a QoS policy for a service provider so they can include it in the design of their MPLS core network. If the design must support an MPLS network with six classes, and CEs will be managed by the service provider, which QoS policy should be recommended?

map DSCP bits into the Exp field

map IP precedence bits into the DSCP field

map flow-label bits into the Exp field

map IP CoS bits into the IP Precedence field

map IP ToS bits into the Exp field

Answer: A

Question No: 200 – (Topic 2)

Which two OSPF design considerations should you implement to support the eventual growth of a network, so that CPU and memory are unaffected by the size and complexity of the link-state database in a large service provider network? (Choose two.)
